For example, Patent No. 3,860,027 illustrates wheels which mount the platform and provide movability to it as well. A further illustration is shown in the remai~'nytwo patents previously cited. In the embodiment illustrated, movement is - provided by wheels 20 which are journaled through an axle 21
3~ to platform support members 22. ~heels 20 can be rubber tired and engage the sur~ace of the earth directly or wheels 20 can be of the type used on a railroad and engage rails 23, for example. The Gpposite side of platform 10 is also supported by ~ 3 --' - ' ~ ~.7~
a truck 25 having wheels 26 journaled thereto which likewise may be rubber tired or ~he type attached for the use on a rail as illustrated in the FIGURE~
Under normal use the platform lO must always main-tain tension through disc 11 against linkage 13~ To accomplishthis the preferred em~odiment uses a winch 30 which is connect-ed through a cable 31 to truck 25. It is obvious of course that control mechanisms can be automatically incorporated in the winch to operate in a manner to always maintain a pre-determined amount of tension on platform lO. Such a controlis well known and will not be further described here.
In order ~o retain the linkage against disc 11 a plurality of flat portions 32 are formed in its periphery.
These flat portions have a length substantially equal to the length of the links between the pivots 33. In the embodiment illustrated, five links are shown between each of the carts 14. Three of these links are provided with corresponding flat portions 32 formed in the periphery of disc 11. In order to prevent the linkage from dropping or rising during the 180 bend and thus become disengaged from disc ll, a plurality of linkage engaging means 34a and 34b are attached to the ~5 ;' q~
periphery above and below the midpoin~ of the flat por-tions formed on the periphery of disc 11. The spacing between the linkage engaging means is the same as the vertical dimension of the linkage in the preferred em-bodiment. The spacing is accomplished by making thedisc 11 dimensionally equal to the vertical height of the linkage. Since there may be some slight misalign-ment of the linkage when it is in a position to be trapped by linkage engaging means 34a and 34b, 34b is made having a sloped portion 3S. To assist in the transition be~ween ~he slope portion 35 and a nonslope portion 36 a plurality of friction reducing roller bearings 37 are implanted into the sloping portion 35 of linkage engaging means 34b. To further assist in the positioning of linkage 13 prior to being trapped by linkage engaging mean 34a and 34b, a linkage guide means 40 is mounted on each side of platform 10 and has journaled therein a first roller 41 which is hori-zontally journaled and spaced above platform 10 so that the linkage 13 will be at the proper height just prior to being trapped by linkage engaging means 34a and 34b.
Movemen~ ~rom slde to side of linkage 13~is also re-strained by a second roller 42 and a third roller 43, vertically journaled in linkage guide mean~ 40 and at-tached to ngage the opposite sides of linkage 13. Thus,rollers 41, 42 and 43 give two~dimensional positioning to linkage 13 in uring that it will be in proper position to:be trapped:by linkage engaging means 34a and 34b.
A notch re~erred to by arrow 45 is formed into disc 11 and is cut deep enough to accept the portion of the cart 14 facing the disc 11 which generally would com-prise all of tEle cart 14 bisected by a plane passiny through the linkages 13. It is obvious, of course, that the diameter of the disc 11 must be calculated to provide an e~ual spacing of notches 45 and flat por,tions 32 so that continued rotation of disc 11 will have a corresponding notch 45 and flat portion 32 and each cart 14 and link 13 that is to be moved -through the 180 bend. In the illustration three notches are shown.
Obviously, if rnore width is permitted, disc 11 could be pro-vided with four or more notches 45.
Operation The 18Q bend operates as follows. The conveyor ismoved into position in, for example, a mine, where the slurry hoses 17 and 18 are utilized. The linkage 13 is threaded through guide means 40 above roller 41 and between rollers 42 -and 43. Disc 11 is then rotated to permit cart 14 to pass into notch 45. Disc 11 will then continue to rotate, moving link-age 13 onto flat portions 32 so that it is trapped between linkage engaging means 34a and 34b. Once the system has 2assed completely around the conveyor, it is moved to the point where the slurry hoses 17 and 18 are coupled to the end use apparatus. As more hose is utilized, the platform 10 will move on wheels 20 and 26 down track 23. When the apparatus is to be retracted, winch control means 30 will apply tension pulling platform 10 by applying force to truck 25. As platform 10 moves in either direction disc 11 will rotate permitting the linkage to move through guide means 40 and into engagement with disc 11 on one side and release it from disc 11 on the opposite ~0 side. Xegardless of the direction of rotation of disc 11 the operation is identical; namely, that the linkage is passing through the guide means 40 and being trapped against disc 11 by linkage engaging means 34a and 34b and against flat portions 32 on one side and being re-leased in the reverse order on the opposite side. As previously mentioned, if the linkage should be slightly low the bent down portion of 35 will ~rap the linkage and move it up the low resistance roller bearings 37 into engagement with 1at portion 32.
_onclusions A preferred emhodiment of a 180 bend conveyor has be n illustrated which provides for a positive coupl-ing of the linkage duxing the conveying process through lS the bend portion. The preferred embodiment has been illustrated using a platform 10 undernea~h wheels 14.~
It is obvious, of course, that an overhead platform can be used equally well as illustrated in Patent No.
- 3,860,027 and this invention is no~ so limited as to be restxicted to a single form of support for disc 11.

Thus,rollers 41, 42 and 43 give two~dimensional positioning to linkage 13 in uring that it will be in proper position to:be trapped:by linkage engaging means 34a and 34b.
A notch re~erred to by arrow 45 is formed into disc 11 and is cut deep enough to accept the portion of the cart 14 facing the disc 11 which generally would com-prise all of tEle cart 14 bisected by a plane passiny through the linkages 13.

As platform 10 moves in either direction disc 11 will rotate permitting the linkage to move through guide means 40 and into engagement with disc 11 on one side and release it from disc 11 on the opposite ~0 side. Xegardless of the direction of rotation of disc 11 the operation is identical; namely, that the linkage is passing through the guide means 40 and being trapped against disc 11 by linkage engaging means 34a and 34b and against flat portions 32 on one side and being re-leased in the reverse order on the opposite side. As previously mentioned, if the linkage should be slightly low the bent down portion of 35 will ~rap the linkage and move it up the low resistance roller bearings 37 into engagement with 1at portion 32.
